Statistics Descriptive statistics i.e. mean, standard deviation and frequency distribution will be calculated for each variable in the study. To compare the two groups, Student 't' test (quantitative) and chi square test (qualitative) wherever applicable will be applied. To see trend within the variable 2-way analysis of variance (parametric as well as non-parametric, whichever is applicable) will be done post-hoc analysis. P value < 0.05 will be considered as statistical significant. Statistic software SPSS 7.5 for Windows will be used for statistical analysis.
